VRLA stands for Valve Regulated Lead Acid, which means that the batteries are sealed. Gas will escape through the safety valves

only in case of overcharging or cell failure.

VRLA batteries are maintenance free for life.

AGM stands for Absorbent Glass Mat. In these batteries the electrolyte is absorbed into a glass fibre- mat between the plates by

capillary action. As explained in our book ‘Energy Unlimited’, AGM batteries are more suitable for short-time delivery of high

currents than gel batteries.

Because of the use of lead calcium grids and high purity materials, Victron VRLA batteries can be stored during long periods of

time without recharge. The rate of self 2% per month at 20°C. The self-discharge is less than -discharge doubles for every

increase in temperature by 10°C.

Victron VRLA batterie

s can therefore be stored for up to a year without recharging, if kept under cool conditions.

Victron VRLA batteries have exceptional discharge recovery, even af

ter deep or prolonged discharge.

Nevertheless repeatedly deep and prolonged discharge has a very nega on the service life of all lead acid batteries, tive effect

Victron batteries are no exception.

The rated capacity of Victron AGM and Gel Deep Cycle batteries refers to 20 hour discharge, in other words: a discharge current

of 0,05 C.

The rated capacity of Victron Tubular Plate Long Life batteries refers to 10 hours discharge.

The effective capacity decreases with increasing discharge current (see table 1). Please note that the capacity reduction will be

even faster in case of a constant power load, such as an inverter.

Our AGM deep cycle batteries have excellent high current performance and are therefore recommended for high current

applications such as engine starting. Due to their construction, Gel batteries have a lower effective capacity at high discharge

currents. On the other hand, Gel batteries have a longer service life, both under float and cycling conditions.

The most common charge curve used to charge VRLA batteries in case of cyclic use is the 3 step charge curve, whereby a -

constant current phase (the bulk phase) is followed by two constant voltage phases (absorption and float), see fig. 3.

During the absorption phase the charge voltage is kept at a relatively high level in order to fully recharge the battery within

reasonable time. The third and last phase is the float phase: the voltage is lowered to standby level, sufficient to compensate for

self-discharge.

•

During the bulk phase the current is kept at a constant and often high level, even a

fter the gassing voltage (14,34V

for a 12V battery) has been exceeded. This can lead to excessive gas pressure in the battery. Some gas will escape

through the safety valves, reducing service life.

• Thereafter the absorption voltage is applied during a fixed period of time, irrespective of how deep the battery has

been discharged previously. A full absorption period after a shallow discharge will overcharge the battery, again

reducing service life (a.o. due to accelerated corrosion of the positive plates).

• Research has shown that battery life can be increased by decreasing float voltage to an even lower level when the

battery is not in use.

• Battery Safe Mode

In order to prevent excessive gassing, Victron has invented the ‘Battery Safe Mode’. The Battery Safe Mode will limit

the rate of voltage increase once the gassing voltage has been reached. Research has shown that this will reduce

internal gassing to a safe level.

• Variable absorption time

Based on the duration of the bulk stage, the charger calculates how long the absorption time should be in order to

fully charge the battery. If the bulk time is short, this means the battery was already charged and the resulting

absorption time will also be short, whereas a longer bulk time will also result in a longer absorption time.

• Storage mode

After completion of the absorption period the battery should be fully charged, and the voltage is lowered to the

float or standby level. If no discharge occurs during the next 24 hours, the voltage is reduced even further and the

battery goes into storage mode. The lower storage voltage reduces corrosion of the positive plates.

Once every week the charge

voltage is increased to the absorption level for a short period to compensate for se

lf-

discharge (Battery Refresh mode).

When a battery is not frequently deeply discharged, a 2 step charge curve can be used. During the first phase the battery is -

charged with a limited current (the bulk phase). Once a pre-set voltage has been reached the battery is kept at that voltage (the

float phase).

This charge method is used for starter batteries in vehicles and in uninterruptible power supplies (UPS).

The charge voltage should be reduced with increased temperature. Temperature compensation is required when the

temperature of the battery is expected to be less than 10°C / 50°F or more than 30°C / 85°F during long periods of time.

The re

commended temperature compensation for Victron VRLA batteries is 24 mV /°C for a 12V battery). -4 mV / Cell (-

The centre point fo

The charge current s C (20A for ahould preferably not exceed 0,2 100Ah battery).The temperature of a battery will increase by

more than 10°C if the charge current exceeds 0,2 the charge current C. Therefore temperature compensation is required if

exceeds 0,2C.
